“The Caterpillar Haul Truck Ball Stud Removal Tool has reduced the time to remove ball studs from 12 hours per truck to just 1 hour. The risk of damaging jacks throughout the process has also been removed. This initiative represents a significant cost and time reduction while also improving safety for our maintainers.”
